when I recommended the core upgrade for vehicles "that are not daily driven or for owners that live in a cooler climate", this was in reference to the reduced airflow you are likely to see through the denser "Close Mesh Core Configuration" at low air speeds.
For vehicles that are in stop-go traffic or warmer climates, I was told it's quite possible you will see higher water temps, with the use of PWR's core upgrade in daily driving due to airflow restrictions, than you otherwise would with their standard core. In a cooler climate with significantly lower ambient temps, there would be less thermal load on the cooling system, so airflow through the rad' would not be as much of a concern.
However on the race track where you have maximum air speed and thereby full penetration of air through the densely finned 42 mm core, heat transfer properties are much improved over their standard core.
This is where the "Close Mesh Core Configuration" comes into its own, as under the extreme driving conditions of the racetrack, the thermal load on the cooling system will be further reduced, due to the higher efficiency of PWR's core upgrade.
